"Civil War" is a song by the rock band Guns N' Roses which originally appeared on the 1990 compilation Nobody's Child: Romanian Angel Appeal, and later on the 1991 album Use Your Illusion II. It is a protest song on war, referring to all war as "civil war" and stating that war only "feeds the rich while it buries the poor". In the song, lead singer Axl Rose asks, "What's so civil about war, anyway?"

It was released as a single in 1993 in several regions. Several regions in which the single was not released instead saw the release of The "Civil War" EP.

"Civil War" was the brainchild of the Guns N' Roses artists Axl Rose, Slash, and Duff McKagan. Slash stated that the song was an instrumental he had written right before the band left for the Japanese leg of its Appetite for Destruction world tour. Axl wrote lyrics and it was worked into a proper song at a sound check in Melbourne, Australia. On September 27, 1993, Duff McKagan explained where the song came from in an interview on Rockline:

Basically it was a riff that we would do at sound-checks. Axl came up with a couple of lines at the beginning. And... I went in a peace march, when I was a little kid, with my mom. I was like four years old. For Martin Luther King. And that's when: "Did you wear the black arm band when they shot the man who said: 'Peace could last forever'?" It's just true-life experiences, really.

The song was first played at Farm Aid 1990, this was the first and last time the song was played with original drummer Steven Adler. The song was played many times in 1991 and 1992, though after 1992 the song was not performed again until December 4, 2011 at the Bridgestone Arena in Nashville, Tennessee. As of 2014, the song is played at almost every show.
